Nowadays we are promoting high density aquaculture by air blower aerator with microporous tube diffuser for better DO, less investment, but higher production. As our site experiement in Indonesia, one HDLH100 air blower with 15HP motor or diesel engine can supply enough air to 3X1000m2 pond with DO more than 5ppm, one m2 can cultivate 300 PL10, and after 4 month, production is 4000kg. hope you can give us opportunity to quote when you plan to use the air blower aerator, thanks.
